Whenever Reddit hosted r/place, it got instantly dominated by streamers and massive clans covering the canvas in their insignia, anybody else who wanted to draw be damned. I remember in 2022 I was working with a smaller subreddit to try to put a 16x16 graphic somewhere unobtrusive and could scarcely put 3 pixels down before getting overwritten by the German flag that was already taking up 1/3 of the canvas.
On Canvas yesterday, somebody put up a ~50 pixels wide drawing of Princess Celestia fighting Nightmare Moon (something that wouldn't have survived 20 seconds on Reddit before being vandalized) and the people drawing the osu! logo went behind it!
I'm just kind of amazed and stunned and glad that we seem to be infinitely better at silently collaborating and not stepping on each other than the people on That Other Site who are obsessed with pointless internet clout.
Up until they started to try to take down the NCD NATO flag at least
A moderate amount of fighting keeps it interesting IMO.
